The present invention pertains to a machine for setting stay'sor fasteners in contamers such as boxes crates or the l ke.

the machine isles ,eclall desi ned fora t y a plying or setting the type of fastenercovered by my Patent No. 1.692 596, datedNovember 20, 1928, this type lof fastener being constructed so that it will connect a rack strip and a side of ,a crate and when set, serves to grip both of these members and thus prevents bulging ofthe side iof the container. As the rack strips or partitions of thesecrates form its principalstrengthening or reinforcing means, it is important that they :be se- ,cnrely fastened to the sides of the crate. It is therefore the primary purpose of the pres- 1611b machine to rigidly sand firmlysecure the fastener in place.

A further iinpontam-t object is the designing of a machine whichanot gonly serives to ef- .ficiently set the fastener .inthe parts pf the cy-rates which it connects together, but performs this fanction qnickly gand neatly. .It is also intendedto provide a machinepfsimpie, durable constrnctionin the operation of whichhighlyslrilledemployees are notl necessary.

Other objects .will appear hereinafter.

A practical embodiment of the invention is disclosed in the accompanying drawings, Tarherein, 5

Themachine comprises ,a base 1 on which is rigidly mounted an upright framework made up of verticalposts 2,3and transverse connecting membersdfi and16. Mounted for limited vertical :reciprocatory movement on the upper portions of member-s2, 3 is a horivzontal cross member 7 :having an integral, forwardly extending arm 8 projecting centrally from the front face thereof. Gross member 7 is provided at each end with a renm'ovable i beaning plate 7. whereby it may be n-secured in place for sliding movement lip :and down on the npright member .2, 3 ,of the frame of the machine. As shown clearly in Figs. Land ,4, npperarm 8 is provided on one of its faces avith a horizontal rib 9, the upper face of which has aformed therein a ilongitndi nally extending tapered groove 10 a which ,isniopenat tlie olglteiwencl of,-the arm for a pnr-pose wvhich will appear hereinafter.

Gonnectedcentrally vto the rear face of the cross member 7 by means of a suitable pin 11 is aconnect ing 13od12, which is disposedin an I being disposed. eccentrically on the gear wheel so as to form a common crank and connecting rod connection between gear 14 and upper cross member 7.

Gear wheel 14 is keyed to the forward end of a horizontal shaft 15 mounted in suitable bearings 16, 17"fastenedto the top of base 1. Also mounted on suitable bearings 18, 19 on the top of base 1 and parallel to shaft 15 is a secondhorizontal shaft 20.0n the forward end of which is keyed a spur gear 21 with which gear 14 'on shaft 15 meshes.

Mounted for free rotation on shaft 20 is a gear wheel 22 which'is driven in a counterclockwise direction, as-indicatedI-in Fig.4, by an electric motor 23 through a spur gear 24. Referring toFig. 4 again, it-will beseen that this results in clockwise rotation o'f'gear wheel 14 looking from the front of the machine.

There is also mounted on shaft'20 a collar 25 which is keyed to theshaft for rotation therewith, but is free to slide longitudinally on the shaft. Secured to theadjoining face 7 of gear wheel 22 is an expanding shoe clutch 26, the operative parts of which are connected by toggles 27 with collar 25'so that the clutch is engaged when the collar is moved towards "ear Wheel 22. Cooperating with collar 25 IS the usual. shipperlever 28, whereby collar 25 may be-moved toengage clutch 26. At its lower end shipper lever 28-is pivotallyconnected to base 1. Intermediate its ends there 1 and thus driving gear wheel 22, engagement of the clutch will result in motion being transmitted to gear'wheel 14, which, as heretofore stated, rotates in a clockwise direction as indicated by the arrow in Fig. 4. The parts as they appear in this figure are in their normal inoperative positions, namely, the positions which they automatically assume when the parts come to rest after a fastener setting operation. At this time pin 13, whereby rod 12 is connected to, gear wheel 14, is at thehighest pointthat it reaches during the operation of the machine, and consequentlyupper cross member 7 and its arm'8 are in their extreme upper position;

As shown in Figures 1, 4 and 5 there is mounted on horizontal shaft'15 a collar 33 provided with a transversely projecting arm 34. Arm 34 is adapted to be secured in any desired angular position on shaft 15 by means of a set screw 35 mounted in collar 33. The

purpose of arm 34 is to provide automatic means adapted to act on a cooperating portion 36 formed on the adjacent arm of shipper lever 28 to disengage the clutch 26 and stop the machine upon the completion of each fastener setting operation. In the normal or inoperative position of the parts shown in Figs. 1, 4 and 5, lever 34 has just passed out of engagement with the cooperating portion 36 of shipper lever 28 after operating upon the same to cause disengagement of clutch 26 The cooperating surfaces of arm 34 and portion 36 are shaped suitably, of course, to bring about the desired action.

In order to aid in automatically bringing i wardly projecting arm 41 is located in the machinebelow upper cross member 7 and its forwardly projecting arm 8, and is adapted also to be reciprocated upwardly and downwardly intermittently during the operation of the machine. During this movement, cross member and its arm are guided in part by uprights 2, 3 of the machine frame for which purpose each extremity of cross member 40 is provided with a rearwardly projecting extension 42, see Fig. 12, to the rear faces of which is removably secured a plate 43. Lower cross member 40 and its arm 41. receive their movement through upper cross member 7 and its corresponding arm 8 when the latter are operated by connecting rod 12. For this purpose, upper and lower cross members 7, 40 are connected together at each side of the machine by a rod 44, the lower endof which is fixed by means of a set screw or the like in a perforated lug 45 provided on lower cross member 40. At its upper end, rod 44 extends through a perforated lug 46 on upper cross member 7 and has a spacer tube 47 loosely mounted thereon above lug 46. A stop collar 48 is secured on the upper end of rod 44 by a set screw or other suitable means and is adapted to be engaged by tube 47 as upper cross member 7 ascends t0 raise lower cross member 40 to its uppermost position. Mounted on rod 44 and interposed be tween lugs 45 and 46 is a coil spring 49 which, as will appear hereinafter, permits continued downward movement of upper cross member 7 and its arm 8, after lower cross member 40 and its arm 41 have reached their lowermost position.

Mounted in the machine below lower cross member 40 and its arm 41 is an adjustable table 50 having a pair of brackets 51, 52 formed on its under side and provided at 'justed then on table- 50 and plungerhead 86 and jaw carrying member-63 adjusted on arms Sand '41, so that, When-arms 8 and 41 movedownwardlyto perform a fastener setting operation, side wall93 of the crate will project freely into slot '73-and: partition 92 of the, crate into slot 71 in the under faceof 'the jaw carrying mechanism, as shown in Fig. 5. f

;Before'operatingthe machine to set a fastener in place in the crate, it must be adjusted for the height of' the particular size of crate being used. This is accomplished vertical'adjust-ment of -table 5O-through hand wheel 60; First, it is necessary to set the machine in motion-by depressing pedal 32.

This throws in clutch 26 and through" the interconnected mechanism causes downward movement of arm's8 and 41, the movement of the arms being in'synchronism for the first portion oftheir downward travel. As shown in Fig.4,when the arms are in their upper- I *most position, they are separated by gravity and by coil springs 49,49, so that spacing (125" collars 47,47 abut stop collars 48, 48 at their upper ends. The arrangement andproportiming of the parts is such that, in this position, fastener setting plungers 7 4, 75 and 77 are in their outermost and fully retracted positions in order to freely receivethe upper edges of the crate 92 when the fastener setting mechanism is lowered; r

stated, arms 8 and41 at first move downwardly together, but as soon as lower cross member comes in contact with the upper edge of the stationary cross member 5, member 40 becomes stationary- As long as arms 8 and 41 move together, the fastener settlng j aws 7 4, 75 and 77 remain in their fully retrac'ted position as shown in Fig.4. "However, with the arrangement described, when cross member 40 and its arm 41 come to a stop, upper cross member 7 and itsarm 8, by

' reason of coil springs 49, 49 are permitted to continue their downward movement. This results immediately in slmultaneous inward movement of fastener settingjaws 74, 75 and 77 through the inclined ribs and grooves before described.

With the machine thus operating, hand wheel 60 is manipulated so as to raise or lower table 50 and the crate thereonuntil the upper edges of the crate are but a slight distance below the under face of jaw carrying memis made of sheet metal, comprises a bodyportion 96 having an extension 97. On the sides 'ofbody portion 96there are formed integral depending tongues 98, 99 and end extension 97 base similar tongue 100 arranged at right angles to the first mentioned tongues. Each .of the three tongues, 98, 99 and 100, is provided at its lower end with inturned spurs 101 adapted toiengage firmly the material of the crate when'the tongues of the fastener are: bent inwardly to secure the fastener thereon. 'It will be clear that the body portion 96 and tongues 98, 99 of the fastener engage the partition 94 of the crate, while extension 97 and tongue 100 are adapted to en-;

gage the side 93 thereof so as to bind these two parts of the container firmly and rigidly together. The form of the fastener 95 before it is set by the machine is shown clearly in FigsJl and 4. In this condition, it will be noted thatthe tongues 98, 99 and 100 are flared outwardly somewhat so as to permit thefastener to be slipped readily over the upper edges of'the crate.

With the fastener 95 so positioned on thecrate, the operator depresses pedal 32, as a result ofwhich the fastener setting mechanism carried by arms 8 and 41 descends until partition 94 and side 93 of the-crate are disposedwithin intersecting slots 71, 73 of the fastener setting mechanism. 9 At this time it is impossible for the fastener to slip out of place due to the presence of jaw carrying members 63, 64. As soon as cross member 40- strikes transverse member 5, arm 41 stops... and the continuing movement of upper arm 18 results in fastener setting jaws 7 4, 75 and 77 moving inwardly until their inner ends are brought into engagement with the depending Side tongues 98, 99 and 100 of the fastener. jaws 74 and'7 5, which are disposed in alignment with each other, are brought thus simultaneously into engagement with the corresponding side tongues 98, 99, causing the tongues to be-bent inwardly until their spurs lOlare embedded firmly in partition 94 of the crate, see Fig. 8. Simultaneously, end jaw 77 at its inner end engages with the end tongue 100 of'the fastener and bends it inwardly until the spurs 101 thereon are embedded firmly in the outer face of side wall 93 of thecrate. Theoverhanging curved lip 78 on jaw 77 acts on the fastener at the j uncture of its extension 97 and end tongue 100, so as to shape and bind this portion of the fastener tightly about the upper edge of side wall 93 of the crate, and thus draw the partition wall 94 into close engagement therewith, see Figs. 6 and 9.

Upper arm 8 then ascends, causing fastener setting jaws 74, 75 and 77 to be retracted simultaneously. As soon as spacer tubes 47 47 engage stop collars 48, 48, arm 41 and the fastener setting mechanism carried thereby also ascend until all of the parts again assume the normal or inoperative posi tion of Figs. 1 and 4t. The machine is stopped automatically at this time by reason of the disengagement of clutch 26 caused by the eamming action of arm 34 on projection .36 provided on shipper lever 28. As appears from Figs. 1. i and 5, the momentum of the parts of the machine is sufhcient to carry arm fi-l-ii; beyond the lowermost portion of projection 36 after which brake band 38 serves immediately to stop the mechanism. In other words the complete cycle of operations neces sary to set a fastener in a container is performed automatically by the machine as soon as the operator depresses pedal 32. The machine then comes to rest automatically in readiness for a repetition of the cycle of operations.

Reference is now had to the modification shown in Figure 10. Considerable frictionbetween the parts is caused by the operation of inclined ribs 85 on plungers 83 in the inclined slots 79 in the fastener setting jaws 74, 75 and 77. In order to reduce this friction and to permit more efficient operation of the parts, in some cases it may be desirable to mount an anti-friction roller 102 in each of the jaws 74, 75 and 77 so that the roller projects slightly 'into the inclined slot 79 and into engagement with th under surface of the inclined rib 85. Slot 79 should be somewhat Wider than rib 85 in order to permit proper coaction between the parts. Preferably, anti-friction roller 102 is mounted for free rotation on a small shaft 108, j ournaled at its ends in the sides of slot 104, which opens on one side into inclined slot 79.

It will thus be seen that the machine described is designed for eiiicient and quick application and setting of fastenersin boxes, crates, or the like.
